Photovoltaic activity in a ZnSe/PEO-chitosan blend electrolyte junction
Abstract Thin films of ZnSe and PEO–chitosan blend polymer doped with NH4I and iodine crystals were prepared to form the two sides of a semiconductor electrolyte junction. ZnSe was electrodeposited on indium tin oxide (ITO) conducting glass. The polymer is a blend of 50 wt% chitosan and 50 wt%...

| description | Abstract Thin films of ZnSe and PEO–chitosan blend
polymer doped with NH4I and iodine crystals were prepared
to form the two sides of a semiconductor electrolyte
junction. ZnSe was electrodeposited on indium tin oxide
(ITO) conducting glass. The polymer is a blend of 50 wt%
chitosan and 50 wt% polyethylene oxide. The polymer
blend was complexed with ammonium iodide (NH4I), and
some iodine crystals were added to the polymer–NH4I
solution to provide the I−/I3−redox couple. The room
temperature ionic conductivity of the polymer electrolyte is
4.32×10−6 S/cm. The polymer film was sandwiched
between the ZnSe semiconductor and an ITO glass to form
a ZnSe/polymer electrolyte/ITO photovoltaic cell. The open
circuit voltage (Voc) of the fabricated cells ranges between
200 to 400 mV and the short circuit current between 7 to
10 μA. |
